SVATONOVICE — so you can call this toy consist of scoreboard and console, mounted in the same enclosure. The scoreboard is a screen of frosted glass, behind which square cells are bulbs designed for safe voltage (not more than 6.3).
Next to the scoreboard controller switches, which you can use to light a certain lamp or several, in the right combination, making any figure: house, car, letter.
